I can't help you with a "safe destruction" protocol. The best method
I've heard of IMHO was to pass all ethidium solutions through an
activated charcoal column. When the column has reached capacity make a
new one and have the old one incinerated. Although I recommend this, I
don't do it. (A very, cherry blush.)
